Gear device with torque-dependent and stepless modulation of gear transmission ratio whereby gear is mechanical gear and transmission modulation is based on relative movement between shaft and sleeve

摘要

Gear device is customized for torque-dependent and stepless modulation of gear ratio. The gear is a mechanical gear. The gear transmission ration is decreased with increasing torque. The transmission modulation is based on a relative movement between a shaft (1) and a sleeve (4). An independent claim is also included for a gear device system.
